Therefore, it is necessary to improve the system to ensure the safe and stable operation of the system under various environmental conditions. CONTENT OF THE UTILITY MODEL

[0005] The traction power supply return current monitoring system with moisture-proof and heat dissipation functions provided by the application adopts the following technical scheme:

[0007] By adopting the above technical scheme, the temperature sensor can monitor the temperature in the main box body, when the temperature in the main box body exceeds the set value, the heat dissipation mechanism starts to work to reduce the temperature in the main box body, thereby reducing the influence of high temperature on the normal work of the devices on the mounting plate and prolonging the service life of the devices, and the drying mechanism can dry the external humid air sucked in by the heat dissipation mechanism during work, thereby reducing the influence of the humid air on the devices on the mounting plate.

[0008] Optionally, the heat dissipation mechanism comprises an air inlet fan, an air outlet fan and a controller, the main box body comprises an upper box body and a lower box body, the mounting plate is mounted in the upper box body, a communication opening is arranged between the upper box body and the lower box body, an air inlet is arranged at the bottom of the lower box body, and an air outlet is arranged on the side wall of the upper box body.

[0009] The air inlet fan is arranged on the communication opening, the air outlet fan is arranged on the air outlet, and the temperature sensor, the air inlet fan and the air outlet fan are electrically connected with the controller.

[0010] By adopting the above technical scheme, the communication opening, the air inlet and the air outlet arranged between the upper box body and the lower box body of the main box body are arranged, and ventilation and heat dissipation are realized. The air inlet fan and the air outlet fan work cooperatively under the instruction of the controller. When the temperature sensor detects that the temperature in the box body is too high, the controller starts the air inlet fan and the air outlet fan to dissipate heat, air is introduced into the air inlet, hot air is discharged from the air outlet, and an effective air circulation and heat dissipation path is formed. Through the structure design, the system can quickly and effectively reduce the temperature in the box body, and overheating of the device is avoided.

[0011] Optionally, a flow guide air inlet plate for guiding air at the air inlet to the communication opening is arranged in the lower box body, and the flow guide air inlet plate is arranged in a converging manner from the air inlet to the communication opening.

[0012] A flow guide air outlet plate for guiding air in the upper box body to the air outlet is arranged in the upper box body.

[0013] By adopting the above technical scheme, a stable air flow path is formed when air is introduced and discharged, the flow guide air inlet plate guides air at the air inlet to the communication opening, cold air flows to the upper box body, and uniform cooling of the internal equipment is facilitated; and the flow guide air outlet plate guides air in the upper box body to the air outlet, and ensures that hot air is smoothly discharged.

[0014] Optionally, a damping frame is arranged in the upper box body, damping mechanisms are arranged between the damping frame and the upper box body and the mounting plate respectively, the mounting plate is covered in the damping frame, and an air guide opening opposite to the flow guide air outlet plate is arranged on the damping frame.

[0015] By adopting the above technical scheme, the mounting plate is covered by the damping frame, and is fixed between the box body and the mounting plate through the damping mechanisms. When the equipment is subjected to external impact or vibration, the damping frame and the damping mechanisms can absorb and relieve the vibration transmission to the internal mounting plate, and protect the stability of the devices thereon. Meanwhile, the air guide opening is arranged on the damping frame and is opposite to the flow guide air outlet plate, and the heat dissipation air flow is not affected. This structure effectively improves the anti-vibration capability of the system, and increases the reliability of the equipment in harsh environments.

[0016] Optionally, the damping mechanism comprises a first damping spring, a second damping spring and damping pads, and each of the first damping spring, the second damping spring and the damping pads is provided with a plurality of groups;

[0019] Optionally, a drying box is mounted on the air inlet, a plurality of flow holes are formed in the upper and lower walls of the drying box and communicated with the inside of the drying box, and a drying agent is arranged in the drying box.

[0020] By adopting the above technical scheme, the drying box is arranged at the air inlet, the drying agent is arranged in the drying box, and a plurality of flow holes are arranged on the upper and lower walls of the drying box to ensure the flowability of the air before and after passing through the drying agent. The humidity of the air is reduced after passing through the drying agent, and the air enters the main box body, thereby preventing the internal devices from being dampened due to the direct entry of the external damp air. The arrangement of the drying box realizes the pretreatment of the air before entering, ensures the dryness of the air in the main box body, and effectively prolongs the service life of the internal devices.

[0021] Optionally, a blowing fan and a heating element are arranged on the air guide inlet plate and correspond to the drying box, the heating element is located between the air outlet end of the blowing fan and the drying box, and the blowing fan and the heating element are electrically connected with the controller, and the blowing fan can heat and dry the drying agent in the drying box after absorbing moisture through the heating element.

[0022] By adopting the above technical scheme, the blowing fan and the heating element on the air guide inlet plate can heat and regenerate the drying agent in the drying box. When the drying agent is saturated, the blowing fan heats the air through the heating element and blows it into the drying box, promotes the evaporation of the moisture of the drying agent, and realizes the regeneration function of the drying agent. This design prolongs the service life of the drying agent, avoids frequent replacement, improves the maintenance efficiency of the system, and ensures the persistence of the moisture-proof function.

[0023] Optionally, dust screens are arranged on the air inlet and the air outlet, and the dust screens are located between the drying box and the air inlet and between the air outlet fan and the air outlet.

[0024] By adopting the above technical scheme, the dust screen can effectively block the external dust from entering the box body, protect the internal devices from being polluted by dust, ensure smooth air circulation, prevent the heat dissipation channel from being blocked due to dust accumulation, and further improve the protection capability and heat dissipation effect of the system.

[0025] Optionally, a dust prevention channel is arranged between the air outlet fan and the air outlet, the dust prevention channel extends from the upper box body into the lower box body, and a dust outlet is arranged on the side wall of the lower box body and communicates with the bottom of the dust prevention channel.

[0026] By adopting the above technical scheme, when air enters from the air outlet of the upper box body, it will first enter the dust prevention channel, at this time, the air flow will drive the dust to settle at the dust outlet and be discharged, further improving the dust prevention effect. The design of the dust prevention channel and the setting of the dust outlet realize the automatic dust removal function, effectively reduce the influence of dust on the heat dissipation channel, and ensure the long-term stable operation of the system.
